Add upper boundary checks for tilt sensitivity settings

The tilt sensitivity values were passed to the NVS module without
the boundaries being checked, even though the maximum
percent value is 100. This commit fixes this issue.
Also test cases are added to cover the upper boundary checks
for the tilt sensitivity settings.

Fixes #1086
